Quality has never been an issue for Smalling, who has seen injuries prevent him from performing and playing on a consistent basis, but the 25-year-old is now fit and firing under Van Gaal's leadership after coming out on top against Aleksandar Mitrovic in a physical battle during last week's goalless draw with Newcastle United.

"I have always liked that competition with the striker and obviously Daley is not that sort of centre-back who is going to dominate, so it's a case of I take that mantle on and I am enjoying it," said Smalling.

"I wouldn't say I hadn't done it previously in games because I feel like I bullied quite a few players in matches.

"But it's a case of making sure there is that consistency and, hopefully, I can get that consistency where it can be on show every week.

"I feel like I am playing well and I am enjoying my football.

"It is good to keep playing each game and knowing that there are not too many changes at the moment because we are doing well, so I hope to keep that up.

"It's comfortable playing next to Daley. Sometimes if there is a big opponent we will swap around. But he can handle himself as well so I am enjoying playing alongside him."
